Background: Atypical myopathy (AM) is an acute, severe rhabdomyolysis occurring in grazing horses. Since In the beginning of October 2009, a new outbreak affects started in several European countries. Geographic, demographic and clinical data of the reported cases in the month October 2009 are described. Key Findings: The survival rate over the month October 2009 was 25%. The most frequently observed clinical signs were congestedive mucous membranes, dyspnea, tachycardia, depression, weakness, stiffness, recumbency, trembling, transpirationsweating, and myoglobinuria. Non-survivors were significantly more often likely to be recumbent than survivors. Prognostic factors, symptomatic treatment and preventive measures are discussed. Significance: Slight differences were encountered during the described outbreak of AM in October 2009 compared to previous studies. Equine practitioners should be alert aware that previous epidemiological studies have shown that after a high prevalence this autumn, for new cases are likely to occur in the upcoming spring 2010.

This case report describes a periarticular abscess and a suppurative arthritis of the atlanto-occipital joint in an adult horse. The horse showed a painful swelling localized on the atlanto-occipital region and ataxia in all four limbs. During his hospitalization the horse developed recumbency, dysphagia, facial paralysis and seizures. With the use of ultrasonography of the atlanto-occipital region a tentative diagnosis was made which was later confirmed by autopsy. Culture of the abscess revealed a Staphylococcus aureus. However, the horse had a history of recurrent fever, hypertrophy and abcessation of the submandibular lymph nodes, neck pain and dyspnoea for 2 months, suggestive for strangles. [less ▲]

Cardiomyopathies in cattle are disorders that are sometimes encountered by rural practitioner. They usually lead to cardiac dysfunction, heart failure, arrhythmias and even sudden death. Most of cardiomyopathies in cattle are of hereditary, nutritional or toxic origin. Bovine cardiomyopathies may involve only one animal as they may affect several animals of the farm and can cause considerable economic losses either in treatment costs, decrease of zootechnical performances or in mortality. The etiological variability of cardiomyopathies as well as non-specificity of clinical signs often complicate the diagnostic approach of the practitioner. In this paper, a literature review on cardiomyopathies that may occur in cattle is proposed. Their different aetiologies and clinical aspects as well as diagnostic means in affected cattle are discussed [less ▲]

Introduction : La description pratique de la technique de biopsie rectale dans l’espèce équine diffère d’un auteur à l’autre. Pour obtenir des échantillons représentatifs, il est souvent suggéré effectuer les biopsies à l’aveugle au moyen d’une pince à biopsie utérine plutôt que par endoscopie rectale. Les sites de prélèvement préconisés sont variables. Même si tous les auteurs s’accordent à dire qu’il faut réaliser la biopsie en arrière du cul-de-sac rétropéritonéal [1] [2], la distance de prélèvement en avant de l’anus varie de 15 cm [2] [5] à 30 cm [1] [3]. De plus, le prélèvement est réalisé tantôt au plafond [1] [5], tantôt au plancher [3] du rectum. De nombreux auteurs évoquent le très faible risque de complication suite à la biopsie rectale [1] [4], mais la perforation, l’abcès périrectal et la péritonite septique ont été décrits [2]. Objectifs : Le but de cette étude est d’évaluer les risques associés à la technique de biopsie rectale réalisée au moyen d’une pince à biopsie utérine. Méthodes : Cette étude a été effectuée sur 11 chevaux destinés à l’euthanasie : les 7 premiers ont été biopsiés sous anesthésie générale, et les 4 autres ont été biopsiés debout sous tranquillisation (0,01mg/kg détomidine IV ou 0,6mg/kg xylazine IV). Résultats : Aucun des 4 chevaux biopsiés debout n’a montré de signes de douleur au cours de la procédure. Pour un droitier, il s’est avéré plus facile d’effectuer la biopsie rectale avec la pince dans la main droite et la muqueuse rectale dans la main gauche et de prélever à 2H. Discussion et conclusions : La biopsie rectale est facile à faire et bien supportée sur le cheval tranquillisé, bien qu’elle soit fréquemment associée à des hémorragies locales. Le prélèvement devrait être fait à moins de 15 cm de profondeur pour réduire les risques de péritonite. Il est en outre conseillé d’effectuer les biopsies à 10H (gaucher) ou 2H (droitier) pour faciliter techniquement l’acte et réduire les risques d’hématomes. Attendu que l’euthanasie a été effectuée juste après les biopsies, le développement éventuel d’autres complications n’a pas été évalué dans cette étude. Dans une étude suivante, l’aspect histologique des prélèvements obtenus par biopsie sera évalué et comparé à celui obtenu post-mortem. References 1. BRAZIL T.

The horse is particularly prone to myopathies, which can be acquired or inherited. The history and clinical signs of myopathic horses are of major importance for their diagnosis, but they can be quite aspecific, complicating the diagnosis. Often complementary exams, as rectal exploration, locomotory and/or neurological examination, blood and urine analysis, are necessary to distinguish a myopathy from other conditions. When the presence of a myopathy is confirmed, ideally its origin should be determined. The origin can sometimes be suspected by specific elements in the signalment, history and/or complementary exams, but often needs to be confirmed by the histological examination of a muscle biopsy and/or genetic tests.

Bioavailability and pharmacological effects of tiludronate were compared when administered as an intravenous (i.v.) bolus at a dosage of 0.1 mg/kg body weight (b.w.) once daily for 10 consecutive days (group 1, n = 6) and as a single constant rate infusion (CRI) at a total dose of 1 mg/kg b.w. (group 2, n = 6) in healthy adult horses. Tiludronate and carboxy-terminal cross-linking telopeptide of type I collagen (CTX-1) were measured in plasma and urine. There was no statistically significant difference in area under the curve (AUC) and clearance (Cl) between the two groups. Bioavailability of the CRI was 103% (not significantly different) that of the 10 daily i.v. bolus doses. Cumulative urine tiludronate excretion could not be compared between groups because of poor sensitivity of the assay in urine. Plasma and urine CTX-1 levels were not different between groups throughout the study. However, interindividual variations were greater in group 1 than in group 2. A significant decrease in CTX-1 levels was observed in plasma after the first administration in group 1, but not in urine; while in group 2, a significant decrease in CTX-1 concentrations was observed after treatment in both plasma and urine. In conclusion, both dosage regimens of tiludronate produced similar plasma exposure and pharmacological effects in adult healthy horses. [less ▲]

Polyneuritis equi (PNE) is a rare neurological disease in the horse. Because of the suspicion in PNE of a T-lymphocyte mediated immune response against the myelin, the objective of this study was to determine the composition of the inflammatory infiltrate in the involved nerves of 3 horses with PNE, studied retrospectively. T-lymphocytes were demonstrated in the lesions, which suggests a T-lymphocyte mediated immune response against myelin. In addition, the presence of B-lymphocytes indicated a local production of antibodies. More research, involving a prospective study, is needed to determine whether the T-lymphocytes are cytotoxic or T-helper lymphocytes. [less ▲]
